Question

我有以下代码用于根据状态对表信息进行排序。

$query = "SELECT * FROM affiliate_tasks WHERE username = '$_SESSION[username]'";

if( isset($_POST['sort-selection'] && $_POST['sort-selection'] != 'all' ) ) 
{
   $query .= " AND status = '". $_POST['sort-selection']."';" ;
}

$result = mysqli_query($con, $query);

当我运行网页时，它给了我这个错误：

Parse error: syntax error, unexpected T_BOOLEAN_AND, expecting ',' or ')' in /home/content/38/10473938/html/website/panda/affiliates/task.php on line 60

第60行如下：

if( isset($_POST['sort-selection'] && $_POST['sort-selection'] != 'all' ) ) {

我无法弄清楚代码有什么问题，任何帮助都会受到赞赏！

Answer 1

看起来好像你在那一行的错误位置有结束括号..

if( isset($_POST['sort-selection'] && $_POST['sort-selection'] != 'all' ) ) {

应该是

if( isset($_POST['sort-selection']) && $_POST['sort-selection'] != 'all' ) {

Answer 2

结束括号中有语法错误

if( isset($_POST['sort-selection']) && $_POST['sort-selection'] != 'all' ) 
                                //^this one was missed and added at the end

使用mysql数据库信息排序表的代码
